As noted in today’s Jolt, if you look at this survey on voter contact . . .

Democrats also have modest but still notable leads in voter contact in North Carolina and Colorado, two states that look like must-wins for Democrats to hold the Senate.
The Republicans still have a lead in the fight for the Senate, even though the Democrats appear to be out-campaigning them in more states. That’s because the Republicans have built leads in Arkansas and Louisiana, where the effectiveness of the campaigns seems fairly balanced, and Alaska, where the Begich campaign’s advantage on the ground hasn’t overtaken the Sullivan campaign’s advantage in advertisements.

It’s a red flag for Republicans. But I’d rather see a red flag in the first week of October, when there’s still a month to address it and catch up, than in the first week of November.

Also note these aren’t enormous differentials in voter contact — 6 percentage points in Colorado, 9 in North Carolina.

The same pollster has Democrat Udall up 3 and Democrat Hagan up 1 — so the voter-contact spread is bigger than the polling spread.
