In a speech on the Senate floor today, Minority Leader Mitch McConnell of Kentucky will praise and welcome a group of Tea Party protesters rallying on Capitol Hill.Politico has a preview of the speech, which comes after Senate President Harry Reid blamed the Tea Party from blocking compromises in congress. “In my view, the tea party has had an overwhelmingly positive impact on the most important issues of the day,” McConnell, of Kentucky, will say, according to prepared remarks. “It’s helped focus the debate. It’s provided a forum for Americans who felt left out of the process to have a voice and make a difference. And it’s already leading to good results.”
