This could either be a great idea for the Democrats or could backfire in the worst way. Trump can dig up a lot of dirt on Obama's presidency, as well. It's one of those high risk/high reward tactics. I look forward to seeing where this leads.
What dirt? They tried tarnishing him in 2012. Since then, there hasn't been anything worse than before 2012's election that would do any damage. Democrats have very high approval ratings of Obama, so either way it doesn't matter.
Obama has been a decent president overall and no amount of Trump blowing through his piehole will change that Bushie
I agree, President Obama has the political capital, so why not spend it wisely. I'm just saying it comes as a high risk/high reward investment.
