For me it was the 1972 General Election. I was as strong supporter of George Stanley McGovern at the time. Nixon won by a landslide, with McGovern taking only Massachusetts and the District of Columbia.
72 was my first as well. Mr McGovern got my vote as well. He took my state (Massachusetts) and DC as well. Nixon took everything else. I guess that is what you call a landslide.
The first election I voted in was the 1976 Presidential election between Carter & Ford, voted for Carter - after then I developed a personal policy of voting against ANY incumbent and ANY republican - for instance, this year I'll be voting for the Libertarian for president, whoever it is. I would LOVE to see Jesse Ventura run for president, but he's a lot smarter than that.
1992 Presidential Election- I voted for Clinton
2008 Presidential election. I was excited. lol
I think it was the year McGovern ran for President. I was actually an RFK supporter until he was assassinated.
