If John McCain won the election of 2008 how would he do in 2010 and 2012?

[Pericles]

The 2010 midterms would be pretty bad for the GOP, hard to compare with the irl 2010 midterms on a seat by seat basis but Democrats would definitely retain a solid House majority, probably make notable gains, and gain Senate seats and governorships (so they would have state level dominance for redistricting rather than the GOP, but I doubt they would or could gerrymander as aggressively as the GOP did, though even Democratic tilting maps would be a tremendous boost from the irl maps). In 2012, it's possible McCain doesn't run for re-election, depending on how his health is affected by the presidency, since he would be pretty old. However since his health did hold up pretty well until 2017, he probably does run, in which case he suffers the fate of Bush Sr (and probably at the hands of Hillary given Democrats would see Obama's nomination as a mistake if he lost and she runs as a populist and has much greater appeal to non college-educated white voters). After three terms in the White House it would be very hard for the GOP to win again, especially given the economic circumstances which they'd take the full blame for (while Obama could convincingly argue he had done his best to clean up the mess Bush made), and McCain's economic response imo would be less effective than Obama's with a weaker stimulus and possibly the auto industry goes under (which would kill him in the Midwest). President Hillary probably wins re-election in 2016 on the back of the economic recovery, but could suffer harsh losses in the 2014 and 2018 midterms (though her coalition may not be as bad for midterms as the Obama coalition was).
