1. The article on Donald Trump's attack on Jon Tester portrays Trump as aggressively attacking Tester with personal insults, calling him a 'radical left lunatic'. However, it doesn't provide any context for these accusations or offer an opportunity for Tester to defend himself. This creates an imbalanced perspective.

2. The article suggests that Jon Tester is in a tough re-election campaign. While it is factual, the emphasis seems to be on Trump's opposition to Tester rather than the political reality of a Senators' re-election struggles.

3. The article also provides some background to the issues Trump and Tester are battling over - including immigration policy, the border wall and the Keystone XL pipeline. However, it doesn't delve deeply into these issues nor does it give an insight into the rationale behind these policies.

4. The use of language and description such as "Trump also criticized Tester’ physical appearance, remarking, “He’ got the biggest stomach I have ever seen.”" does seem to add to the sensationalism of the article, without providing much value.

5. Overall, the article lacks a neutral perspective and tends to lean towards one side of the political divide, which undermines its credibility. It fails to present a well-rounded analysis of the issues at hand.
