Even if Trump’s ratings are looking slightly less dire than they were a few months ago, I’m still bullish on the Democrats’ chances. I recommend that you take the 1.15 (87%) on the Democrats in Delaware. Not only is this a state that Hillary Clinton carried comfortably two years ago, but the incumbent Senator Thomas Carper has an approval rating of 58%. The Republicans’ lack of confidence is shown by the fact that they haven’t been able to attract any top-quality candidates.
Pennsylvania should also be relatively straightforward for the Democrats. Even though Trump narrowly managed to carry the state at the last election, its senator Bob Casey has had consistent leads of around 15% in the polls over his opponent, Lou Barletta. I therefore think that the offered odds of 1.19 (84%) on Betfair are generous, and you should snap them up.
Similarly, in Wisconsin Democrat Tammy Baldwin has double-digit polling leads against the two potential Republican challengers, which should see her through. I’d therefore bet on the Democats winning this race at 1.29 (78%).
