FOR WHAT IT'S WORTH ON THE HUNDREDTH DAY OF BIDEN. Here is some data from the Rasmussen Reports Daily Presidential Tracking Poll for the last three presidents.

Each chart has three sets of data: green represents the percentage of approvals; red, disapprovals. They sum to 100%. The data in black is the Rasmussen Approval Index (scale on the right), calculated as the difference between those who Strongly Approve and those who Strongly Disapprove, which usually is about 70% of the total polled.

Here's Obama: Obama started with a very strong approval rate, but after 100 days his approval was close to divided at about 55%/45%, and his approval index dropped (along with total approvals) from plus 30 to near zero.

And Trump: His first 100 days were chaotic -- the typical initial honeymoon, followed by the usual drop. Disapprovals peaked in late March, then began a decline. At the end of the first 100 days, the rates were close to 54%/46%, with disapprovals dominating. The approval index dropped to a low of about -20 in April, recovering to about -10 at 100 days.

And finally Biden: He promised a 'boring' presidency, and largely succeeded. Approval/disapproval rates have consistently been right at the 50% mark, a sometimes little over, sometimes a little under. His approval index has consistently been below zero, slowly declining to the -10 level today.

Make of it what you will.
