Perhaps a liberal hero (i.e., center-right to right). But, not the left.

The left includes socialists and communists, for example. With anarchists and (the original[1], left) libertarians at the far left. Many countries have Socialist and Communist parties with representation in government. The political spectrum in the US is truncated at it's left somewhere around center-right in part due to first-past-the-post elections which tends to devolve into a two party system. But, the far-right fascists and their fellow travelers and (right) libertarians are well represented. Also in part due to corporate media propaganda-- see Eugene V. Debs (a socialist) and the role Hearst media's false reporting had in preventing his election (the same Hearst media that was instrumental in starting the Spanish American war with its false reporting). Of course, the US throughout its history has tended to imprison, expel, and execute folks on the left who rose to prominence too.

Just look at the policies of the so-called "left" presidents in the US:

Clinton: Basically 3rd and 4th term of Reagan. Welfare reform (aka gutting social safety net), prison reform (partially responsible for the current American Gulag with the US imprisoning more in absolute numbers and as a percentage of population of any country-- Clinton signed the federal 3-strikes law into being. Illegal wars in the Balkans. Aggressive stance against Russia-- snubbing Russian attempts to join Nato, and expanding Nato to Russia's doorstep against agreements made in Bush Sr. administration with Moscow (current Ukraine war is arguably the result). Pushed neoliberal policies of Reagan (neoliberalism is the economic policy of the right to privatize everything, provide open boarders to capital while closing boarders to humans, and de-regulate business and finance-- this last one directly setup the circumstances that allowed the 2008 financial crisis to occur; Clinton signed the repeal of Glass Steagall). Illegal sanctions against Iraqi people-- responsible for the death of half a million children under the age of 14 per UNICEF (Clinton's secretary of state Madeleine Albright said this death toll of children was "worth it".

Obama: Attempted to gut social security benefits by redefining the way cost of living adjustments were made. Continued illegal wars of aggression and illegal sanctions. First president known to order the summary execution of an American citizen (the man's young US citizen son was also executed by Obama's drone attacks; A Trump commando team executed his even younger US Citizen daughter). Obama's crowning achievement, his health insurance law ACA was actually originally proposed by the far-right Heritage Foundation during Clinton's tenure-- it ensures that private corporations will continue to reap huge profits at the expense of ordinary Americans-- actual access to healthcare seems almost an after-thought. Huge proponent of privatizing education.

Biden: His proposed domestic policy had much more veneer of the left than I'd have expected from his time in the Obama administration (probably due to Sanders), but his politically right colleagues in the Democratic party prevented passage (perhaps by design; this always seems to happen when progressive / pro labor legislation is proposed by a Democrat-- it usually isn't even proposed unless Democrats have a minority so its defeat is certain). His foreign policy is solidly on the right, though. Continuing illegal sanctions on 1/4 to 1/3 of the entire world's population. I haven't seen any figures yet, but his sanctions against Afghanistan were predicted to kill 1M people primarily children this last winter. His administration has actively worked against a negotiated end to the war in Ukraine.

These are solidly right-wing policies. We have right and a far-right parties. The left has zero representation.

[1] libertarianism, a left ideology that grew out of anarcho-syndicalism, but the right seems to have co-opted the term.
