Uhh, yah, you clearly don't know what you are talking about.
Gore and Kerry both got well over 60% of the vote in RI.
Laffey is polling more then 20% behind the D.
Chafee is worthless, so I don't care all that much who wins the primary, but you shouldn't be dellusional, it would take divine intervention for Laffey to win the general.
Rhode Island is not as hopelessly Democrat as you suppose, and it is not averse to electing moderate-to-conservative Republicans such as Laffey---in fact, Governor Carcieri is no less conservative than Laffey, and he was elected with 55% in 2002. Kerry is from next-door Mass., and he got 59.42% in RI. For the sake of comparison, President Bush got 62.86% in North Dakota in 2004, and that hasn't stopped liberal-to-moderate Democrats Conrad and Dorgan from being elected to the Senate.
Laffey will be the underdog against Whitehouse, but I think he's got a shot at the upset. Pay no heed to polls taken before he defeats Chafee; the general election campaign won't begin until the day after the primary.
