John Boehner's resignation spells trouble for Jeb Bush

As if Jeb Bush needed another problem.

House Speaker John Boehner's abrupt resignation Friday -- after an insurrection by grassroots activists infuriated at the failure of Washington Republicans to thwart President Barack Obama -- was another bad omen for a campaign wilting amid anti-establishment fury.

In the 2016 presidential race, outsiders are in, insiders are out and the messy power struggle that is splintering the GOP is going to make winning the nomination -- and then capturing the White House -- very tough for a party standard bearer like Bush.
