National polls move to Obama

By ChimbaChumba

ChimbaChumba’s PollOfPollAverages” (national polls)

Pollster    46.5 - 44.9  =  Obama   +1.6%  (y’day +1.9%)  

CNN          46.0 - 42.0  =  Obama   + 4.0%  (no change)

RCP           47.2 - 44.3  =  Obama   + 2.9%  (y’day +1.8%)

538 EP      48.8 - 48.0  =  Obama    + 0.8  (no change)

Gallup       48.0 - 42.0  =  Obama    +6.0  (y’day +1.0) 

ChimbaChumbaAverage: Obama +3.06%  (y’day +1.90%)

Big bounce for Obama today, mainly on the back of Gallup. Is this the start of the traditional “convention bounce”, or is that icing on Obama’s cake yet to come? Bear in mind historically DEM “poll convention bounces” have been 7-9% (Carter, Mondale, Dukakis and Gore). Clinton 2000 was +16%! Only the hack Kerry in 2004 broke the cycle, going minus! This makes the next 10 days a tricky period for punters, until we see polls about 1 week after the GOP convention. You have to decide whether poll movements are meaningful, or a temporary aberration. But the uncertainty creates opportunity for the punter that reads it right. As mentioned a few days ago, I think McCain is over the odds, but recommend waiting to see if the betting market misreads what might be a mere convention bounce that causes McCain’s price to drift unduly. But it takes balls of steel to back McCain when Gallup (the gold standard) has Obama +6.0%. As you can see below, McCain’s price has drifted a little. Optimum timing for a bet might be about 3-5 days from now, when DEM convention bounce (if there is any) has seeped fully into the polls. But remember, Conventions and VEEP’s is not when this election will be decided; assuming Obama doesn’t roll over McCain on back of Bush/Cheney backlash, the election will be ultimately decided when the debates start - if debates go one way or the otehr the polls will follow. Only once debates start can we put faith in the polls and make a clearer assessment of the odds for each horse.

Betting Market (Betfair):  Obama $1.58, McCain $2.80 (y’day $1.64, $2.74)

ChimbaChumba’s Daily “PollofPollAverages” in key battleground states, and the Electoral College vote tracker

The first poll on this blog measures the average of national polls. In this section we keep a daily watch on state polls in Ohio & Colorado, two key battleground states. Every Saturday we expand the analysis to 8 battleground states. In this section we also include a daily update of the Electoral College vote count from all states, awarding the electoral votes for each state based on today’s poll average for each specific state (i.e. disregarding the national polls). 
ChimbaChumba’s Daily Poll Average - Ohio & Colorado
McCain’s lead in Ohio a little down, Obama’s lead in Colorado a little up (sigh - exact opposite of y’day). No change to overall EV situation, with Obama still winning the Presidential election on the back of Colorado.
The numbers shown in our Ohio/Colorado table below refer to Obama’s margin + or -
                                                          Ohio                           Colorado                                                             
RCP                                                    -1.2  (no change)        +0.4   (no change)
Pollster                                            +1.7  (y’day +1.3)       +1.8   (y’day +1.7)
538 (trend-adjusted)                -1.2  (no change)          +0.8   (no change)
CC’s PollOfPollAverages:  -0.23 (y’day-0.36)     +1.0  (y’day +0.96)

ChimbaChumba’s Electoral College Vote Tracker

Obama: 260 EC votes + New Hampshire(4) + Colorado(9) = 273 EC votes (no change)
McCain: 227 EC votes + Ohio(20) + Virginia(13) + Nevada(5) = 265 EC votes (no change)

ChimbaChumba says - Obama still “wins” the election based on current state polls, with Colorado the state tipping him over the line. The other states currently within circa 1% are Virginia, Nevada and New Hampshire. If New Hampshire switched to McCain it would be 269-269 - a deadheat!! If its a tie, Obama wins coz DEMs own the most states in the Congress. An interesting question for punters to consider, is whether Colorado polls have been influenced by DEM Convention being in Colorado? If that is effecting the polls, is it a temporary aberration that will disappear by election day, or will it hold? Given Colorado is currently the tie-breaker, working out what Colorado polls mean is crucial to betting on the right horse.
