> If you are elected to congress, your job is to get bills passed.
This is a vast oversimplification. Your job is to represent your consistuents. In many cases, this means your job is to stop bills from getting passed, especially in the current political situation.
> The more the left supports Bernie, the more people like Warren struggle to get elected
This is a very strange take. Sanders and Warren are mostly close allies and rarely compete. Both are successfully elected Senators, from separate states. Warren declined to run for President in 2016 and appeared to be supporting Sanders. In 2020 they both ran for President, but guess what, neither one of them won the Democratic nomination. In any case, it's important to recognize that elections are popularity contests and not competency tests, as should be obvious from our current President.
The issue is not even "the left." Sanders is more popular than Warren, indeed more popular than almost any politician of any party (including male politicians, if you insist on making this about gender), among political independents. Because of his popularity among independents, he's the most popular politician in the US and would have a better chance of winning the Presidency than any Democrat (of any gender), but the Democrats nonetheless refuse to nominate him. If Warren were equally popular among independents, then Democrats should nominate her, but she's not. Of course this lack of popularity among independents is not specific to Warren: most non-Democrats dislike Democrats.
In 2016, Sanders put up an unexpectedly stiff challenge to Clinton, who was considered an overwhelming frontrunner at the beginning of the race. The natural next step for the left would be to build on that momentum and push Sanders over the top in 2020. In my opinion, it's quite delusional to expect that the left would for some bizarre reason abandon Sanders in 2020 and throw their support behind Warren instead. That would make little sense. Why start over from scratch? In any case, I doubt that Warren would have fared better. The establishment doesn't want a leftist, no matter who, and they quickly conspired to consolidate around Biden, who didn't even pick Warren as his running mate.
