Are Ohio and Iowa still battleground states?

2010 and 2014 were very red years for these states in the midterm elections.  However, it can be risky using midterm data to predict presidential elections.  Then in 2016 neither of these states were competitive even though Democrats thought Clinton would win Ohio by 8 and she lost by nearly double digits.  I guess they were almost 20 points off in their Ohio polling.  Anyways,  in 2008 we saw Missouri basically tied in an election Obama won by a good margin.  Iowa was a purplish-blue battleground state, but in 2016 was just red while Missouri has basically become like Kansas and Nebraska.  Is the mid-west trend going north disqualifying Iowa as a battleground state?  Is Minnesota next say in 2024?  Last yea Minnesota was already center-right for the first time since the 50's.  Then we have Ohio who always votes for the winner but is never 10 points from center.  Has the West Virginia trend bled its way throughout Ohio and western Pennsylvania?  Will Pennsylvania be light red by 2024?  Or will Ohio and Iowa go back to their purple selves?
