Is Bernie Sanders is going for too much

I feel like he simply is saying too much to do. They all seem like big changes and then there is a lot of them and I don't see a whole lot of them happening, so I'm not really down for supporting him yet. I probably would if it were more possible and not a little too good to be true.

What do you think about this thought?

So much of the platforms of Bernie Sanders and Elizabeth Warren require total control of the houses of Congress to the point that a majority of what they're campaigning on is a non-starter in terms of ability to be implemented. Theres no way that Universal Healthcare or massive gun control measures will pass the Senate with the needed 60 votes because the GOP will not compromise on either of those issues (at least to any degree Warren or Sanders voters would be satisfied with) and the Dems wont win enough Senate seats to give the party a super majority to pass whatever legislation they want. 

A large number of the states with Senate races in 2020 are contests where Dems simply dont have a good chance of winning.... Arkansas, Alaska, Georgia, Iowa, Kansas, Kentucky, Mississippi, Tennessee.... Most races take place in states that are so inherently Republican that no Democrat has a feasible chance of flipping the seat..... Some organizations think that there are only 4 seats where the seat can be flipped, and one of them is a Democrat seat at risk of flipping back to the GOP:

Arizona - GOP

Colorado - GOP

Maine - GOP

Alabama - DEM

Assuming that Senate seat in Alabama flips back to being Republican, if the Dems win in Arizona AND Colorado AND Maine, then that results in the Senate only swinging two more seats into the favor of the Democrats, putting the total at 51-49 for the Dems (This is counting 2 Independents who usually caucus with the Dems)..... Thats simply not enough of a majority to ram major legislation like gun control or universal healthcare through Congress in order for it to be signed by the President. 

Whether the policies proposed in the first place is sensible or too far to the left is one thing, the simply math in the Senate that needs to be done for there to even be a chance of the legislation being passed is something else entirely. A majority of their platforms simply cannot be enacted without some sort of massive voter shift in GOP stronghold states flipping the senate seats to the other side, meaning that a majority of their platforms are unobtainable fantasy, regardless of the merits or motivations behind them. 

2022 is the only election where Dems stand to make enough gains where they can even think of enacting major legislation championed by the more liberal faction of the Dem party... Ohio, Pennsylvania, Wisconsin, North Carolina, Florida..... All of those states are FAR more competitive in terms of party support in both states than most of the states with senate races this cycle. Yet even if Dems clean up in 2022 and managed to get gains in 2020 and win the presidency in 2020 as well, it still may not be enough to get to the 60 vote super-majority needed to ram whatever legislation they want through Congress, assuming that everybody votes the party line as well

socialism is a hard sell, you have to try and disguise it, with that in mind, listen to what he says again and you'll see what I mean.  I can't remember how many trillions he'll spend just on the climate change stuff, but everything else "free" will pile onto that huge debt.

California is proof positive that you don't need the federal government's help to go full socialist.

Its a contest, who can be the most radical
