Wrong! So wrong! Perry was on record back in 2010 clearly stating that the last time he voted for a Democrat for president in the general election was in 1976 when he voted for Carter. He admits he was fooled by Carter - Southern Democrat, farmer, Christian - he though Carter was a conservative Dem.
Concerning working for Al Gore in 1988:
“[John] Sharp countered by noting that in the race for the Democratic presidential nomination in 1988, Mr. Perry was co-chairman of Mr. Gore’s Texas campaign. Mr. Perry acknowledged that but said there was a ‘push to get a conservative Southerner’ elected president.” (Sam Attlesey, “Link to Bush separates Perry, Sharp,” The Dallas Morning News, 9/15/98)
Sorry, the facts do not bear out your contention. Perry voted for Reagan twice and for Bush41 over Dukakis, all before becoming a Republican. He was a "Reagan Democrat", like so many other Southern Democrats. Now that you know the facts, I assume you will cease making this scurrilous charge and apologize.
