Angry rhetoric in a tortured race to the White House has a price, and this is it. From Pew Research Center:
The Republican Party’s image, already quite negative, has slipped since last fall. Currently 33% of the public has a favorable impression of the Republican Party, while 62% have an unfavorable view. Unfavorable opinions of the GOP are now as high as at any point since 1992.
In October, 37% viewed the Republican Party favorably and 58% viewed it unfavorably. The decline in favorability since then has largely come among Republicans themselves: In the current survey, 68% of Republicans view their party positively, down from 79% last fall.
By contrast, public views of the Democratic Party are unchanged since October. Currently, 45% of the public has a favorable impression of the Democratic Party, while 50% have an unfavorable opinion.
The key is in that second paragraph. Even Republicans have grown more dissatisfied with the state of their party. You have to wonder if per-capita alcohol consumption at a political conventions has ever been measured. And whether Cleveland is about to shatter that record.
