If properly vetting a candidate winds up undermining support for that candidate, I'd say that them's the breaks.
I can understand that it's got to sting, seeing the missteps of ones' favored candidate being aired in public, but it's a necessary part of the electoral process in a free republic.
Some of the things being revealed may be unpalatable to us, but as long as they're factual (and not manufactured), it's vital that we familiarize ourselves with that information in order to make an informed choice down the road.
And lest you get the wrong idea, I'm not looking for any candidate to be 100% perfect. We'll never see that candidate in our lifetimes. We do, however, have to know the extent of every candidate's pluses and minuses.
Perry has been vetted for years. He was elected three times as Governor of Texas and has served honorably for 11 years. Over that time frame I've read all the relevant and outstanding news items about Perry. In recent weeks I've seen a lot of frivolous posts personally attacking Perry. Along with innuendo, rumor and gossip but nothing that would disqualify him from being the GOP nominee or potus.
So save you preachy condescension for someone who gives a rats ass.
