So your "evidence" is that you are incredulous? The argument from incredulity?
Point out her current left wing positions. She was on the left for a few things in the past, but what about lately?
Pardon my incredulity at your ignorant take. Honestly, at this point I only have myself to blame to continually underestimating your vacuity.
The Voteview project (now based at UCLA) has, since the 1980s, employed the roll-call votes cast in Congress to locate all senators and representatives on a liberal-conservative ideological map. These data and methods have been utilized by academics in thousands of peer-reviewed books, book chapters and journal articles. Although no method is perfect, there is a general consensus within the academic community that the NOMINATE methodology employed by the Voteview project and its close cousins represent the gold standard.
The Voteview data can be used to study the Senate in two principal ways. The first method analyzes each two-year congressional period separately and provides a unique ideological location for every senator for each biennium, allowing for the comparison of senators who served during that Congress, but not for the comparison of senators across Congresses. The second method analyzes the congressional periods together and provides a single ideological location for a senator based on the entirety of their voting record while in that office, thereby allowing for the comparison of senators across Congresses.
Harris served in the Senate representing California during two Congresses (the 115th and 116th) before resigning to assume office as vice president in 2021.
In the 115th Congress (2017-2019), 48 Democrats served in the Senate and cast a sufficient number of votes for reliable analysis. Of those 48, Harris had the third-most liberal voting record, after Sen. Elizabeth Warren (Mass.) and Sen. Kirsten Gillibrand (N.Y.).
In the 116th Congress (2019-2020), 45 Democrats served in the Senate and cast a sufficient number of votes for reliable analysis. Of those 45, Harris had the second-most liberal voting record after Warren.
Since the turn of the century, there have been 11 complete Congresses (107th through 117th), with only five months remaining in the 118th. During this period, there were 109 different Democrats who served in the Senate and cast a sufficient number of roll call votes for a reliable analysis of their ideological position.
Of these 109 Democrats, Harris has the second-most liberal voting record. This makes her slightly less liberal than Warren, but more liberal than all of the remaining 107 Democrats, and significantly more liberal than all but a handful.
Included among these 109 Democrats are President Biden, former President Barack Obama and 2016 presidential nominee Hillary Clinton. The record indicates Clinton is more liberal than 74, Obama more liberal than 62 and Biden’s more liberal than 52.
I'd offer a graph to show how extreme that is, but I'm too tired to have to explain the graph to you.
The only question is whether you're a gaslighter yourself, and only pretending to be this ignorant, or really this ignorant.
