And, it isn’t just Connecticut that has Republicans scratching their heads. Trump traveled to Maine last week, a state that has also been blue since 1992.

Trump campaign spokesman Jason Miller says their internal polling shows him up in Maine. Plus, Maine awards two of its four electoral votes by congressional district, of which there are two, and Trump is very popular in one of them.

Concerned Republicans say their worries go beyond the campaign’s decision to send its greatest resource — the candidate himself — to chase one or two electoral votes in Maine, or to what they believe are unwinnable states like Connecticut. The other phenomenon perplexing veteran operatives is that the Trump campaign now has the needed money to finance television ads and ground operations — they just don’t appear to be spending it.

The imbalance in ad spending is astonishing. Since the end of the primaries, Hillary Clinton has spent $42.9 million in ads. Donald Trump has spent zero.
