Why are Democrats performing better at the Senate level?

[OSR stands with Israel]

Cause Senate incumbents at this stage have the advantage that voters generally know who their senator is (unlike their house member) and at this stage don’t yet know who their opponent really is . So that creates a pretty big incumbency bump in the polls at this stage .

When it comes to presidential elections both candidates tend to have very high name recognition due to how much free media the election campaign gets and this time this factor is greater than ever due to the election being between two presidents.

When it comes to house elections , both candidates tend to have low name recognition these days so house elections are the closest proxy you can get to voters general partisan preferences. In the old days house incumbents actually used to have good name rec due to local media still being influential and they would generally have command over that . These days local media has little influence so that tool is no longer helpful
