(CNN) Seven-in-10 registered voters say they're extremely or very interested in the November elections, a record high in Fox News polling for their midterm election tracking since 2010.

More Democrats, 77%, say they're interested in the elections, compared with 74% of Republicans and 44% of independents.

The 70% figure for extremely or very interested is a new high. Interest in previous years has come close to that, but only right before Election Day. In late October polls in 2014 and 2010, 68% said they were interested. It's now just the start of July, and already voters have surpassed usual levels of interest.

In a follow-up question, Fox asked if, compared with previous congressional elections, voters thought they were more enthusiastic about casting ballots than usual, less enthusiastic or about the same as usual. Forty-four percent said they were more enthusiastic, 43% said they were about the same as usual and only 10% said they were less enthusiastic.

Republicans were more likely to say they were about the same as usual in terms of excitement, while Democrats believed they're more enthusiastic.
