Final answer:
The Democratic Party is generally in favor of taxation as a means to promote the public good, supporting social services and public initiatives through progressive taxation.
Step-by-step explanation:
The political party that generally believes taxation is necessary for promoting the public good is the Democratic Party. This belief aligns with the party's platform which tends to support the role of government in providing social services and funding public initiatives.
The Democratic Party often advocates for progressive taxation, where tax rates increase with higher income levels to fund government programs that they argue benefit society as a whole. On the other hand, the Republican Party traditionally favors lower taxes, with the perspective that reducing the tax burden stimulates economic growth and individual freedom.
