According to Gallup, Americans who view themselves as conservative 36%. Pretty steady since 1992 only going up and down a point or two. Moderates, 35% down from 43% in 1992, Liberal 25%, up from 17% in 1992. https://news.gallup.com/poll/328367/americans-political-ideology-held-steady-2020.aspx
Now there are many conservatives who don't view Trump as a conservative, just a man without a political ideology. One that went with the ideology of whatever party Trump belonged to at the time which has been many as he has switched parties 7 times and counting. This is especially true with traditional conservatives who are the ones leaving the Trump lead Republican Party. But they're not joining the democratic party, they have moved into the independent column. Now your neo, social, religious, fiscal conservatives and some more different types of conservatives have remained loyal to Trump and his led GOP.
This also shows up in party affiliation/identification numbers. 30% of the electorate identified with the GOP in Nov 2020, today down to 26%. 31% were democrats, the same percentage, 31% who are democrats today. Independents have risen from 36% in Nov 2020 up to 40% today.
Those numbers are dynamic and change month to month, but the trend is away from the GOP into the independent column, not into the democratic column. I would think these never Trumpers or traditional conservatives who fled the Republican Party, their voting habits haven't changed, just who they identify as.
Nov 2020 probably shows this, many never Trumpers voted for Biden and he won by 7 plus million votes. But the never Trumpers then voted Republican down ballot which enabled the GOP to pick up 14 house seats, 2 state legislatures and a governorship.
