Is Iowa still a swing state?

In my own made up terminology, I consider it to be a battleground state but not a swing state.

Swing state: the states that are plausible or semi-plausible tipping point states
Battleground state: the states that could plausibly vote for either party given a particularly good/bad environment

Iowa was the tipping-point state in 2008, which is unlikely for a state with so few electoral votes. Iowa has demographics similar to those of Wisconsin, so if Michigan gets Biden to 264 or so electoral votes and Iowa votes for him by a larger margin than Arizona, Florida, North Carolina, and Wisconsin it would be the tipping-point state.

Iowa gave the majority of its votes for its US House seats, so such is possible.

DEMS arent contesting IA due to its rural population

It is now close.

Its aggregate vote for the House of Representatives was a clear majority for Democrats in 2018. 2010 and 2014 were Tea Party elections, and 2016 is an anomaly for Iowa in Presidential elections.

If the Democrats can lock down Michigan and Pennsylvania solidly, then Iowa's six electoral votes would be enough to win the Presidential election. Iowa has another attraction for Democratic attention: a highly-vulnerable Republican incumbent Senator. She is more likely to lose Iowa than is Trump, as she has only 43% support in the early summer in a matchup with her challenger. An incumbent is a known quantity, and she needs to be at least in the mid-40's by now to have a good chance of re-election. 43% was sort-of-OK at the start of campaign season, which meant that she was within range of winning against the usual challenger if she wages a spirited and competent campaign.
