She will still lose. Democrat is a religion, not a political party in Connecticut.
One of the primary characteristics of Democrat voters is their blind loyalty to the Democrat brand. They seem unable to connect the current deterioration of our way of life with the Democrat policies that caused it. They combine stupidity with a stubborn willful ignorance of cause and effect. So I agree with you a Republican is unlikely to win in Connecticut. Blumenthal could eat a baby on public television and probably only lose 5% of the Democrat base vote
