If the GOP wins Congress in 2010, is Obama more or less likely to be re-elected?

[Bull Moose Base]

Stick to at-least somewhat reasonable premises like "If the Democrats 75 vote edge in the House is trimmed to 35 and their 18 seat edge in the senate is trimmed to 8, how does it affect Obama's chances at re-election?".   Republicans would be in a much better position to obstruct but the public would possibly be wise to it and punish them more than the president in '12.  On the other hand, if Democrats can't sell the message that Republican obstruction is the big problem this November, they may be too poor at communicating to do so 2 years later.
